LXXI, No. 386, bearing date June (3, 1894,

- and in England, No. 12,807, bearing date July 2, 1804,) of which thefollowing is a specification.

The invention relates to the construction of the doors and sides ofsafes, and has for its object to secure an absolute closure of the dooralmost hermetically, so that no heat or air can enter and thatespecially no thief can open it or break it open, even by means of thebest tools.

In the accompanying drawings, Figure 1 is a horizontal section throughthe front part of the safe, the door shut. Fig. 2 shows a a similarsection, the door open.

In making the front edge or side of the right side W of the safethat is,the side to which the door is hingedI use a rolled iron bar A, ofspecial section, which in the main is of channel shape, but the bottomside of which is partly bent upward, the straight parts a c flanking thearch CL, lying at different levels. The side edges a and a of the iron Aare set back, as shown in the figure, by the thickness of thewall-plates wi and wo. The arch to which the arched part 00 of the ironA is bent corresponds to a circle struck from the center of thehingebolt O. Upon the outside of the part a I rivet an iron B, havingresemblance in shape to a sickle, the bent part being also curved to acircle struck from the center of the hinge, but of so much a smallerradius than the arch a that a hollow space is left between A and B ofthe thickness of another sickle-shaped iron C, forming part of the dooritself, and to which I shall refer below. the lock is attached, I formthe front edge of At the left side, to which the side W also by aspecially-rolled iron D of double channel or S-section in the main,

the stay adjacent to the door being made in steps. The left stay d isset back by the thick ness of the plate zvo forming the inner half ofthe Outer side. In a similar manner the corresponding stay at the rightside of the iron D is set back by the thickness of the inner plate u ofthe left side of the safe. This has for its object to get all jointssmooth and flash, so that the outside covering-plates w can be wellfitted thereto.

Correspon ding to the rolled irons A, B and D are shaped the ironsforming the corresponding side edges of the door. To the inner steelplate t of the door T is riveted the T-shaped iron C, having legs ofunequal length and shape, the left leg being as usual, the right onebeing of sickle shape, as mentioned above, the curved part correspondingin thickness and form exactly to the recess formed by the two irons Aand B, the steel platet again, and the bent part o of the iron C,leaving a free space between each other, into which enters thesickle-shaped part of the iron B when the door is closed, as will beseen from Figs. 1 and 2. and to thus form a fourfold joint at this sideof the door, the parts of which work into each other like teeth, and itwill be easily understood that this joint, good workmanship of coursebeing used, will not only resist the tools of burglars, but it will alsoprevent the entrance of heated gases and of fire by the zigzag of thejoint.

At the lock side of the door I form the side edge by means of an iron Eof hook shape. The hook e fits into the recess d of the correspondingiron D. The iron E is riveted to the inside of the steel plate t, andits leg e is bent to a circle struck from the center of the doorhinge O.To the outside of the part e is riveted the plate te, forming theleft-side edge of the door, the plate tr, riveted to the iron C, formingthe right side edge of the same, and the plate tb riveted to te and z5rby angle irons, as shown, forms the back side of the door. The grooveformed between e and te takes up the thick part d of the iron D when thedoor is shut, and from Fig. 1 it will be The irons A B C and the platesw, 7

edge of the hinge side of the safe having a, A

sickle shaped hollow space for a correspond. ingly shaped iron of thedoor to enter into this space when the door is being closed so as toform a perfectly secure joint at the hinge side of the door.

2. In a safe the combination of the specially shaped irons A, B at theright side of the safe With a specially shaped iron C of T section inthe main, and having one leg sickle shaped to form part of the rightside edge of the door, so that the sickle shaped leg c enters into thecorresponding hollow space between the irons A and B when the door isclosed.
